Goal Your objective is to predict the adoption speed classes. For each id in the test set, you must provide a prediction for the AdoptionSpeed . Metric Submissions are evaluated on quadratic weighted kappa between the predicted class and the observed class. We didn't see this evaluation metric in class, but is similar to precision. Here a link for more details: https://www.kaggle.com/c/petfinder-adoption-prediction#evaluation Submission File Format The file should contain a header and have the following format: id,AdoptionSpeed 0118db3a8,2 e5164d828,3 5335bfb38,3 7d835cf7c,1 etc. AdoptionSpeed Contestants are required to predict this value. The value is determined by how quickly, if at all, a pet is adopted. The values are determined in the following way: - 0 - Pet was adopted on the same day as it was listed. - 1 - Pet was adopted between 1 and 7 days (1st week) after being listed. - 2 - Pet was adopted between 8 and 30 days (1st month) after being listed. - 3 - Pet was adopted between 31 and 90 days (2nd & 3rd month) after being listed. - 4 - No adoption after 100 days of being listed. (There are no pets in this dataset that waited between 90 and 100 days).
